The synthetic process and characteristics of organic /inorganic composite 2nd-order NLO materials with modified polyimides was studied in this study with accumulated experiences in the developments of organic/inorganic hybrides NLO materials via Sol-Gel process and in the fabrication of PI. In a detail contents, alkoxy silane dye was made using disperse red1(DR1) with high optical nonlinearity and PI with good thermal stability. The alkoxy silane DR1 will be treated into film form through Sol-Gel process with silane coupling agent. The film form of alkoxy silane DR1-PAA was heat-treatmented after go through the corona poling technique process. So, the of organic/inorganic composite NLO materials of chemical cross-linking structure as highly electro-optic coefficient which results from the formation of imide combination because of excellent thermal stability of imide combination and Si-O combination and stabilization of dye orientation through heat treatment and corona poling technique process.
